I started working at a fast food place when I was 15.. Not a big chain, a little mom and pop chain of 3 places. Our head manager demanded s p i c and span clean. It was hard work, but I had no problem eating there. We cleaned everything regularly. Pulling the grill weekly and cleaning behind it, changing the friers, cleaning out the walk in refrig and freezer regularly, making sure everything was rotated and moved out. Most everything was cooked to order. The only things we didn't cook to order were certain hot dishes, like sausage and peppers, meatballs, and soup. we did breakfast, loved those hand made homefries, made fresh donuts at 4-5 in the morn, burgers, chicken, fish sticks(fried) , steak sandwich, steak on plate We had the big chains move in on both sides and put us out of business.
